He says females’ physical attractiveness is integral to the survival of the human species. “That’s why women wear lipstick and short skirts,” Hef said.

The interview with the Daily News was about the 84-year-old’s new documentary, “Hugh Hefner: Playboy, Activist and Rebel,” which highlights the magazine mogul’s social contributions, progressive politics and philanthropic pursuits.

Hefner — who says he’s gotten lucky with 2000 different women — donated nearly $1 million this year to help preserve the celebrated Hollywood sign. He’s also made a name for himself as an animal rights and autism awareness activist.

He created the Playboy Foundation in 1965, an organization that provides grants to non-profit groups that fight censorship or research human sexuality.

In 1969, Hefner launched a TV show called “Playboy After Dark,” which showcased many black musicians during an era of American history that was marked by racial inequality. Some of the guests included Tina Turner and Sammy Davis, Jr.

He published the first issue of “Playboy,” the men’s magazine that made him famous, in 1953.

Hefner told the Daily News, “I take the greatest pride in is the fact that I’ve played a significant part in the changing of our social and sexual values.”
